The use of TDCs in quantum research
Wolfgang Löffler's project in Leiden, Holland, finds answers to current questions in quantum research. In the process, our fast TDCs facilitate the development of single-photon counting receiver modules which convert single-photon detection events into streams of time tags.
A single photon is now considered to be one of the most suitable candidates for information transmission in future information networks. The photonic quantum technologies are considered to be unique because decoherence hardly plays a role anymore, i.e. when photon losses are minimized. The photon also seems to be the only suitable carrier for data transmission using qubits, as transmission through glass fibers is possible here.
Since an ever larger group of customers for our TDCs comes from quantum research, we will collect information on the use of our products in this area on this website in the future. If you do quantum research yourself and want to tell us about your experiences or have technical questions about the use of our products, do not hesitate to contact us. This applies to all topics of quantum information science, quantum electrodynamics (QED), quantum encryption, quantum key distribution (QKD), quantum computing, etc.
One project that touches on many of these areas of research comes from Holland. Wolfgang Löffler's team is concentrating on the development of a single-photon light source that is placed directly in a light-conducting glass fiber. Applications for such a light source can be found in abundance, e.g. as photonic quantum gates, quantum repeaters, and short-term quantum memories. If you are interested in how micro cavities that host quantum dots can be used to send single photons into glass fiber, please read this article.
